Native Cybersource API Payment Integration

I’m rolling out full Cybersource REST-API processing on both our mobile app and our Laravel/PHP web platform. The flow must stay 100 % native—no hosted checkout—while remaining fast, secure and fully compliant with 3-D Secure.

The UI is already settled; a Sketch file covers every state for the single-page form (name, surname, card number, expiry, CVV) plus the Apple Pay and Google Pay buttons. Only styling hooks will be exposed so the visual layer matches the design pixel-perfectly.

What I need you to wire up:

• Direct REST calls for credit and debit cards, with tokenization and secure storage of saved cards
• Apple Pay and Google Pay sessions, routed through Cybersource’s gateway rather than platform defaults
• 3DS / Secure Authentication handling, including fallback flows
• Webhooks that post back approved or failed transactions and update our own order tables
• A clean sandbox set-up, followed by guidance and scripts to promote the configuration to production

Deliverables are a well-documented Laravel service class (or set of classes), any helper endpoints required by the native apps, and clear implementation notes so the mobile team can consume your JSON responses without guesswork.

I’ll grant access to our repo and the Sketch file as soon as we agree on the milestones. If you’ve integrated Cybersource without hosted checkout before and can prove it, let’s get started.
